Rules for evaluating the homeworks:

Signature: To get the signature, at most 30% of the assigned homeworks can be missed. Since there were 30 exercises, this means that at most 9 can be missed. In other words, the signature will be given to those who SUBMITTED solutions to at least 21 homework exercises - regardless of the score for these submissions.

Final grade: The homeworks are counted into the final grade with 20% weight. For this purpose, the solutions submitted to each exercise are first evaluated with the following code:
• 3 means the solution is correct.
• 2 means the solution is essentially correct, but there is some error.
• 1 means the student started on a good track, but could not solve the problem.
• 0 means the solution is completely wrong.
In the end, these codes are translated into scores using the following rule:
• "correct" (code 3) is worth 1 score,
• "essentially correct" (code 2) is worth 0.8 scores,
• "started" and "wrong" (codes 1 and 0) are worth no scores at all.
So the maximum possible homework score is 30, and the score actually reached will me viewed as a percentage of this.
